How many rational numbers lie between 1/5 and 1/3?
If x is a nonzero rational number, then what is the value of x°?
Which number is largest among
Which number is smallest among
LCM of 12, 6, 18, 24 = 72
Closure property of rational number will be value in:
Closure property of rational numbers is satisfied for addition, subtraction and multiplication.
Closure property : The sum of two rational numbers will be a rational of addition for rational number.
The difference between two numbers is 22 and their product is 240, what is the difference between their reciprocals ?
p – q = 22, pq = 240.
If a : b = 2 : 3, then what will be the value of ab a+b/ab?
Here a+b/ab Dividing Numerator andDenominator by b, we have,
If a : b = 1:2, then =
= 9/2
The sum of two numbers ‘p’ and ‘q’ is 16 and their product is 48, then, =
= 8.24 x 10^{5}
The sum of two numbers is 24 and their difference is 10, then, number, y = 2^{nd} number].
Solution : x + y = 24
The difference between x and y is 10. In other words, x minus y equals 10 and can be written as equation B:
x  y = 10
Now solve equation B for x to get the revised equation B:
x  y = 10
x = 10 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 24
10 + y + y = 24
10 + 2y = 24
2y = 14
y = 7
Now we know y is 7. Which means that we can substitute y for 7 in equation A and solve for x:
x + y = 24
x + 7 = 24
x = 17
So x/y = 17/7
